問題描述

如何使用另一個 .yml 文件更新預先存在的 conda 環境.這在處理具有多個需求文件的項目時非常有用，例如 base.yml、local.yml、production.yml 等.

How can a pre-existing conda environment be updated with another .yml file. This is extremely helpful when working on projects that have multiple requirement files, i.e. base.yml, local.yml, production.yml, etc.

例如，下面是一個 base.yml 文件，其中包含 conda-forge、conda 和 pip 包:

For example, below is a base.yml file has conda-forge, conda, and pip packages:

base.yml

name: myenv
channels:
  - conda-forge
dependencies:
  - django=1.10.5
  - pip:
    - django-crispy-forms==1.6.1

實際環境是通過以下方式創建的:conda env create -f base.yml.

The actual environment is created with: conda env create -f base.yml.

稍后，需要將額外的包添加到 base.yml.另一個文件，比如 local.yml，需要導入這些更新.

Later on, additional packages need to be added to base.yml. Another file, say local.yml, needs to import those updates.

之前的嘗試包括:

使用導入定義創建 local.yml 文件:

creating a local.yml file with an import definition:

channels:

dependencies:
  - pip:
    - boto3==1.4.4
imports:
  - requirements/base. 

然后運行命令:conda install -f local.yml.

這不起作用.有什么想法嗎?

This does not work. Any thoughts?

推薦答案

嘗試使用 conda 環境更新:

conda activate myenv
conda env update --file local.yml --prune

--prune 卸載從 local.yml 中刪除的依賴項，如 這個答案來自@Blink.

--prune uninstalls dependencies which were removed from local.yml, as pointed out in this answer by @Blink.

或者不需要激活環境(感謝@NumesSanguis):

Or without the need to activate the environment (thanks @NumesSanguis):

conda env update --name myenv --file local.yml --prune
